The cell-free supernatant contained soluble FAs after CTL attack. (A) Extractions of the cell-free supernatant indicated that roughly half of the released label was water-soluble oleic acid and that oleic acid-containing lipids were also elevated in the supernatants after cell death. (B) Extractions of cell pellets yielded nearly all oleic acid into the organic phase, where lipids partitioned. A loss in the cell-associated lipid counts was observed after redirected lysis.
